All artists who've reach the highest heights can probably be considered overrated to an extent, even my favorites, because after you reach a certain status a lot of your work is elevated to some degree just because of who you are and a lot of accolades are just automatically attracted to you, and anyways it all comes down to artists you like or dislike most of the time so it's not like it's unbiased or anything, but here are my picks:
-Eminem:
I don't consider him a very good songwriter, I don't believe his metaphors/ general literary techniques are up to par with the other greats, I don't believe any of his albums remotely match up with the quality other "classic albums" measure up to so I can't help but wonder if the status for what makes a good project/good song is lowered for anything involving Eminem, the fact that his name is synonymous with/the go to name for what makes a skilled rapper is disgusting to me, he doesn't belong near some of the rappers I see people putting him over.
-Big L:
Good punchline rapper, overrated in death because of a cult of character/a few select freestyles/hate for a certain other rapper, regularly put into top 10's and 5's without much to go off of, wasn't a good songwriter (with maybe one exception) in my opinion, has the facts of his career manipulated to act as though he was a threat to other artists at the time of his death, and wasn't expansive in his lyrical techniques yet people act as though he was like Lupe Fiasco describes here:

-Pac:
I don't like his voice, I don't like his style, I've never been able to connect with his music, but he obviously speaks to people and at minimum he's a good writer so I don't feel like I'm capable of accurately judging him, this is more in response to the Christ like/daddy status his stanbase has ascribed to him, they're literally a cult.
Here is a band that confuses me.
Arcadia Fire. This is a band who headlines major fests, but I can't even recall a single song. With a fanbase that gets extremely defense anytime you call them out on why are they headlining.
Jay-Z is my biggest case. A completely mediocre whose not bad at anything, but not good at anything either. Dre follows, where their both good producers but Meh rappers.
Lol get this nonsense out of here.
